Hi Product Hunt!
Really cool to see Encode on here. We recently launched for iOS, after launching our Android app in 2016.
Encode is an totally interactive way to learn to code on your iPhone + iPad - no coding experience required! For our iOS app, we have short coding challenges and lessons in HTML + CSS + JavaScript.
Making the app as interactive as possible was really important to me as I always found I remembered and learned more about programming when I was coding. To this end, we let you run, write and experiment with code in a mobile code editor, and automatically provide feedback for your code.
Happy to answer any questions, and I'd love to hear your feedback. Email me at rohan@upskew.com or leave a comment here.

@j_ennychu Thanks Jenny! Making Encode work offline was something really important to us, to make sure it worked whenever you're offline or stuck on a train! 🚂 Feel free to leave any feedback here or via email at rohan@upskew.com
